TUESDAY 31 DECEMBER 1963 365th day
Rcd. [received] 1 FOCUS order Rcd. [received] a letter from Preston Kohn in Philadelphia asking me if I had seen the game RITHMOMARCHY.
At Claude's we played PSYCHOANALYSIS with his kids and ours.
Claude and I played his game - CROOKED BRIDGE ,
Played on a "___" board as [crossed out] Checker board using Three pcs. [pieces] are placed are shown. Then black continues by putting his next piece wherever he wishes and then players alternate placing one pc. [piece]
Object is to form a chain across the board as indicated. Diagonal connections are O.K.
[Drawing to the left of an 8x8 grid board with three dots: a white dot in the 1st column, 4th row; a white dot in the 8th column, 5th row; a black dot on the 5th column, 8th row. There are also four circles outside the board: a black dot north and south of the board; a white dot west and east of the board.]
When connectinged groups are touching each other the player making the play can take off the opponent's group provided: -
They are both divisible by 2; they are both divisible by 3; the player forms a group of 5 which takes anything (no pc. [piece] can be played next to a group of 5 except one that also makes a group of 5, otherwise it would be suicide).
Claude thought a little bigger board would be preferable.
Some of my suggestions: - When the chain is completed the opponent has one final move in which to try & take it off. Any two groups mutually divisible (2:6, 3:12, 7:14, etc.) would take each other. (6:4 then would not take other). Will try it on a 12x12 board.
